Abstract (en)
An ion separation instrument includes an ion source coupled to at least a first ion mobility spectrometer having an ion outlet coupled to a mass spectrometer only ions defining a preselected ion mobility range. In one embodiment, the ion mobility spectrometer is provided with electronically controllable inlet and outlet gates as a function of ion drift time to thereby allow passage therethrough only of ions defining a mobility within the preselected ion mobility reange. In another embodiment, an ion trap is disposed between the ion mobility spectrometer and mass spectrometer and is controlled in such a manner so as to collect a plurality of ions defining a mobility within the preselected ion mobility range prior to injection of such ions into the mass spectrometer. In yet another embodiment, an ion inlet of the ion trap may be electronically controlled relative to operation of the ion mobility spectrometer as a function of ion drift time to thereby allow passage therein only of ions defining a mobility within the preselected ionmobility range. The mass spectrometer is preferably a Fourier Transform Ion Cyclotron Resonance mass spectrometer, and the resulting ion separation instrument may further include therein various combinations of ion fragmentation, ion mass filtering, ion trap, charge neutralization and/or mass reaction instrumentation.
